Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically, to a fuel cell vehicle chassis and a fuel cell vehicle. Background Technology

[0002] A fuel cell tractor is a commercial vehicle that uses a fuel cell as its primary power source. Its basic principle is to utilize the electrochemical reaction between hydrogen and oxygen in a fuel cell stack to generate electricity to power the vehicle. Specifically, hydrogen undergoes an oxidation reaction at the anode, releasing electrons. These electrons travel through an external circuit to the cathode, while hydrogen ions travel through the electrolyte to the cathode and undergo a reduction reaction with oxygen to produce water. The electrical energy generated in this process is used to drive an electric motor, thereby propelling the tractor.

[0003] In the existing technology, the chassis layout of fuel cell vehicles is complex, and components such as control modules, cooling units, braking systems and batteries are all installed separately on the frame, resulting in low integration of fuel cell vehicle chassis and making it inconvenient for fuel cell vehicle chassis assembly and maintenance.

[0027] Please refer to Figure 1 , Figure 2 and Figure 3 The fuel cell vehicle chassis 100 provided in this embodiment includes a main frame 110 and a first integrated bracket 120 and a second integrated bracket 130 disposed on both sides of the front end of the main frame 110. A power system 140 is disposed on the main frame 110. A control module 150 and a cooling unit 160 are mounted on the first integrated bracket 120. A braking system 170 and a battery 180 are mounted on the second integrated bracket 130. The control module 150 is electrically connected to the power system 140. The cooling unit 160 cools the power system 140. The battery 180 provides power to the low-voltage electrical equipment of the vehicle.

[0028] Specifically, the first integrated bracket 120 and the second integrated bracket 130 of this application are made of high-strength lightweight alloy material, which reduces the overall weight of the chassis while ensuring the strength of the bracket, thus improving the vehicle's range. The first integrated bracket 120 and the second integrated bracket 130 are fixed to the front sides of the main frame 110 by bolts. This connection method facilitates installation and disassembly, and makes it convenient for later maintenance and replacement of the brackets and the components mounted on them. By setting the first integrated bracket 120 and the second integrated bracket 130, the control module 150, the cooling unit 160, the braking system 170, and the battery 180 are respectively centrally mounted on the two brackets, changing the situation of dispersed component installation in the prior art, greatly improving the integration of the fuel cell vehicle chassis 100, and making the chassis layout more compact and reasonable. The integrated bracket design allows the pre-assembled integrated brackets to be installed on the main frame 110 during the assembly process, reducing the positioning and installation steps of individual components on the frame, reducing assembly difficulty, improving assembly efficiency, shortening assembly time, and reducing assembly costs.

[0029] The fuel cell vehicle chassis 100 provided in this application includes a main frame 110 and a first integrated bracket 120 and a second integrated bracket 130 disposed on both sides of the front end of the main frame 110. A power system 140 is mounted on the main frame 110. A control module 150 and a cooling unit 160 are mounted on the first integrated bracket 120. A braking system 170 and a battery 180 are mounted on the second integrated bracket 130. The control module 150 is electrically connected to the power system 140. The cooling unit 160 cools the power system 140, and the battery 180 provides power to the vehicle's low-voltage electrical equipment. By using the first integrated bracket 120 and the second integrated bracket 130, the control module 150, the cooling unit 160, the braking system 170, and the battery 180 are respectively and centrally mounted on two brackets, changing the situation of dispersed component installation in the prior art, greatly improving the integration of the fuel cell vehicle chassis 100, and making the chassis layout more compact and reasonable. The integrated bracket design allows for simple assembly process: the pre-assembled integrated bracket is installed on the main frame 110. This reduces the number of steps involved in positioning and installing individual components on the frame, lowers assembly difficulty, improves assembly efficiency, shortens assembly time, and reduces assembly costs. When a vehicle malfunctions and requires repair, the centralized mounting of components on the integrated bracket allows maintenance personnel to quickly locate the bracket containing the faulty component, facilitating inspection, repair, and replacement, thus improving maintenance efficiency and reducing maintenance costs.

[0030] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3As shown, the power system 140 includes a hydrogen supply system 141 mounted above the main frame 110, a drive system, a fuel cell engine, and a power battery module 142 mounted at the bottom of the main frame 110. The fuel cell engine, the power battery module 142, and the drive system are electrically connected in sequence. The hydrogen supply system 141 supplies hydrogen to the fuel cell engine, the fuel cell engine converts the hydrogen into electrical energy and transmits it to the power battery module 142, and the power battery module 142 transmits electrical energy to the drive system.

[0031] Specifically, the hydrogen supply system 141 is located above the main frame 110, while the drive system, fuel cell engine, and power battery module 142 are located at the bottom of the main frame 110. This layered layout makes full use of the chassis space, makes the distribution of the components of the power system 140 more reasonable, avoids mutual interference between components, and improves the utilization rate of chassis space.

[0032] Furthermore, a fuel cell cooling system 190 is provided above the hydrogen supply system 141. The fuel cell cooling system 190 includes multiple cooling fans installed above the mounting bracket, and the fuel cell cooling system 190 dissipates heat from the fuel cell engine.

[0033] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the control module 150 includes an integrated control module 150, a low-voltage controller for the power battery, and a high-voltage controller for the power battery. The integrated control module 150 controls the braking system 170 and the steering system, while the low-voltage controller for the power battery and the high-voltage controller for the power battery control the power battery module 142.

[0034] Specifically, by functionally subdividing the control module 150, each controller can focus on controlling specific systems or components, improving the accuracy and professionalism of the control. The integrated control module 150's centralized control of the braking and steering systems enables efficient coordination of braking and steering operations during vehicle operation; the low-voltage controller and high-voltage controller of the power battery provide targeted management of the power battery, ensuring its performance and safety.

[0035] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the first integrated bracket 120 has a first mounting compartment 121 and a second mounting compartment 122. The first mounting compartment 121 is located above the second mounting compartment 122. The first mounting compartment 121 is used to install the integrated control module 150 and the cooling unit 160. The second mounting compartment 122 is used to install the low-voltage controller and the high-voltage controller of the power battery.

[0036] Specifically, the first integrated bracket 120 has a first mounting compartment 121 and a second mounting compartment 122, with the first mounting compartment 121 located above the second mounting compartment 122. The first mounting compartment 121 is used to install the integrated control module 150 and the cooling unit 160. The integrated control module 150 can monitor and control the vehicle's key systems in real time, while the cooling unit 160 provides cooling for key components such as the power system 140. The second mounting compartment 122 houses the low-voltage controller and high-voltage controller for the power battery, providing comprehensive management of the power battery. The layered design of the first and second mounting compartments 121 and 122 makes the installation of components on the first integrated bracket 120 more orderly, facilitating wiring and piping layout, and also improving signal transmission and heat dissipation between components. By setting up layered mounting compartments, the vertical space of the first integrated bracket 120 is fully utilized, allowing for a rational layout of components with different functions, further improving the integration of the chassis, making the chassis structure more compact, reducing the space occupied between components, and providing more space for the installation and arrangement of other components. The layered installation compartment design allows maintenance personnel to quickly locate the corresponding parts during installation and maintenance. Each installation compartment is relatively independent, with a more spacious operating area, which facilitates the installation, disassembly, inspection and repair of parts, improving work efficiency and reducing maintenance difficulty.

[0037] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the braking system 170 includes an electric air compressor assembly, a dryer tank, an air reservoir, and a braking assembly connected in sequence. The electric air compressor assembly converts outside air into compressed air and then transmits it to the dryer tank for drying. The compressed air processed by the dryer tank is then transmitted to the air reservoir, and the air reservoir delivers compressed gas to the braking assembly.

[0038] The braking system 170 includes an electric air compressor assembly, a dryer tank, an air reservoir, and a braking assembly connected in sequence. The electric air compressor assembly converts outside air into compressed air, which is then sent to the dryer tank for drying to remove moisture and impurities. The dried compressed air is then sent to the air reservoir for storage. When the vehicle needs to brake, the air reservoir supplies compressed air to the braking assembly, driving the assembly to brake. The electric air compressor assembly continuously operates, providing compressed air to the braking system 170; the dryer tank ensures the compressed air is dry and clean, preventing moisture and impurities from damaging the components of the braking system 170; the air reservoir acts as a buffer and storage unit, ensuring a stable compressed air pressure during braking; and the braking assembly uses the compressed air pressure to initiate braking. This complete compressed air processing and transmission process, from air compression and drying to storage, ensures the quality and stability of the compressed air used in the braking system 170, avoids corrosion and wear of the components by moisture and impurities, extends the service life of the components, and improves the reliability and safety of the braking system 170.

[0039] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the second integrated bracket 130 has a third mounting compartment 131 and a fourth mounting compartment 132. The third mounting compartment 131 is located above the fourth mounting compartment 132. The third mounting compartment 131 houses the battery 180 and the air compressor, while the fourth mounting compartment 132 houses the air tank and the dryer. The second integrated bracket 130 has a third mounting compartment 131 and a fourth mounting compartment 132, with the third mounting compartment 131 located above the fourth mounting compartment 132.

[0040] Specifically, the third mounting compartment 131 houses the battery 180 and air compressor. The battery 180 provides power to the vehicle's low-voltage electrical equipment, and the air compressor provides compressed air to the braking system 170. The fourth mounting compartment 132 houses the air reservoir and dryer for storing and drying the compressed air. This layered layout of the third and fourth mounting compartments 131 and 132 allows for a more rational installation of the braking system 170-related components and power supply components on the second integrated bracket 130, facilitating pipe connections and electrical wiring, and also promoting coordinated operation between components. The layered mounting compartment design centralizes the key components of the braking system 170 and the power supply components on the second integrated bracket 130, optimizing the layout of chassis components, further improving the chassis integration, making the chassis structure more compact and orderly, reducing space occupation between components, and improving chassis space utilization.

[0041] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the hydrogen supply system 141 includes a mounting frame with multiple hydrogen cylinders mounted on it. The mounting frame is covered with a skin, and the hydrogen cylinders supply hydrogen to the fuel cell engine.

[0042] Specifically, the hydrogen supply system 141 includes a mounting frame and multiple hydrogen cylinders mounted on the frame. The mounting frame is covered with a skin. The multiple hydrogen cylinders store hydrogen, providing a hydrogen source for the fuel cell engine. The mounting frame supports and secures the hydrogen cylinders, while the skin protects the cylinders and the mounting frame from external damage, while also providing aesthetic and sound insulation. The hydrogen cylinders are connected to the fuel cell engine via pipelines, ensuring a continuous hydrogen supply to the fuel cell engine.

[0043] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the power battery is located between the left and right longitudinal beams of the main frame 110, and is located below the hydrogen supply system 141.

[0044] Specifically, the power battery is placed between the left and right longitudinal beams of the main frame 110 and below the hydrogen supply system 141, which makes full use of the longitudinal and lateral space of the chassis, allowing for more rational planning and utilization of the chassis space, providing more possibilities for the installation and arrangement of other components, improving the utilization rate of chassis space, and helping to achieve a compact chassis design.
